Picked this Bonanza up today at a swap meet in Michigan, Gold paint looks to be original, the swingarm is blue. Seat and tank are original, seat pan looks okay but some holes were cut into it for the seat cover. Tank is very nice.
I really don't know for sure. I just done a search and a blue one that had the same features said it was a BC1500, the one with a hodaka said BC1500SH. Don't know the differences and how to really discern the differences if there are any other than the engine.
